all for Participation and Contributions:


You are invited to participate in an Open Forum about development, operation and use of metadata registries. This is the third in a series of conferences on this topic.

The Open Forum will bring together persons implementing, intending to implement, or otherwise interested in Metadata Registries to:

provide a forum for information exchange

encourage collaboration in the development and exchange of metadata content between registries,

encourage collaboration in the development of metadata registry implementations, and

encourage standards development and other activities extending the state-of-the-art of this technology.

You are invited to participate by attending any of the presentations or by contributing articles/presentations/position papers to be viewed on the Open Forum website.

The Open Forum will focus on metadata registries that are based on international
and national standards including ISO/IEC 11179, Specification and Standardization of Data Elements and ANSI ANS X3.285, Metamodel for the Management of Sharable Data (which is proposed to become Part 3 of 11179).

Metadata registries based on these standards may be World Wide Web (WWW) accessible, using standards such as HTML, XML and the Resource Description Framework (RDF) for both human and machine interfaces. Other related standards include IEEE P1489, Draft Standard for Data Dictionaries for Intelligent Transportation Systems, which is based upon the ISO/IEC 11179 standard and ISO/IEC DTR 15452, Information Technology - Specification of data value domains.

 

 
O

pen Forum Goals:


The central goal of this Open Forum is to share knowledge and experience: describing implementation experiences and discussing requirements for metadata registries based upon related international and national metadata registry standards. This Open Forum will examine emerging techniques and standards for registering metadata and describe what people have done and are doing in their implementation efforts. This will enable experiences to be shared among those who have implementations, those who are beginning to implement, and those who are considering metadata registries.

A related goal is to facilitate the development of collaborative efforts to share metadata between registries. It is highly desirable to share the cost and effort of developing and maintaining standard metadata. Where mutual interests are identified, it is desirable for one organization to take the lead on standardizing particular data elements with other organizations drawing the standard metadata from the lead organization. For example, EPA may take the lead in standardizing data required for environmental reporting of HAZMAT data, with DOT drawing the standard data from the EPA Environmental Data Registry.

A third goal is to engage the standards and technology development communities to introduce and gain comments on new work being initiated by SC 32/WG 2 either internally or in collaboration with other standards organizations such as W3C, OMG, and other JTC 1 Subcommittees. The new work involves extending the capabilities of metadata registries and embedding metadata registries in other technologies, such as CASE tools, dictionaries/encyclopedias, object management systems, agent/mediator/broker information services. The new work also involves the interaction between metadata registries and technologies such as XML/RDF and other Internet languages, concept/terminology structures such as ontologies/taxonomies/thesauri, etc. This part of the Open Forum is more exploratory with presentations that explore potential standards and implementations.

etadata Registries Issues for the Open Forum:


Metadata can facilitate access, use, understanding, and sharing of data across time and space by systematically describing the content, structure, and semantics of data residing in information systems, databases, or files.

Metadata is an increasingly important means for describing data communicated among organizations or between organizations and individuals using a wide array of Internet/intranet and web technologies. Metadata registries are facilities with associated procedures for storing and registering detailed metadata from multiple sources and diverse organizations in a common structured form. The following is alist of topics that we expect to address:

Tutorials. What are the key concepts found in selected ISO metadata  registration standards? Tutorial descriptions will cover the six parts of ISO/IEC 11179 and related standards. This will include the fundamental notions of a data element, a metadata framework for data elements, a model of the metadata attributes, naming and identification issues, classification schemes, value domains, description of a metadata registry, data registration essentials, Registration Authority essentials, etc.

Implementations. What experiences can participants share that will assist us to develop metadata registries? We will describe operational and planned implementations of ISO/IEC 11179 and ANSI X3.285 (which is proposed as a revised Part 3 for ISO/IEC 11179).

Interoperability. How can we develop interoperable metadata registries, so that we can collaborate to standardize metadata? In addition to facilitating development of standard metadata, interoperation could enable the maintenance agency for standard value domains to rapidly disseminate changes, such as changes to the values in enumerated value domains.

Terminology. How do we specify and manage thousands of concepts and the associated linguistic expressions that denote semantic content?

Semantic structures. How do we organize the concepts/terms into structured sets that can be deployed in other software? The concepts/terms can be organized into thesauri and topic trees that can be deployed in search engines. Concepts/terms are used for data element concepts, for data definitions and for value domains deployed in data base management systems. Other structured sets of concepts/terms include controlled vocabularies, taxonomies, and ontologies that may be employed in technology ranging from web enabled forms to intelligent information services comprised of query agents, request brokers, resource agents and other Internet middleware.

Context. How do we accommodate the diversity of languages, naming schemes, and discipline specific terminology that demand alternate forms of   terms used for definitions, names, and value domain representations?

Object data. How do we extend metadata registries to better handle object data? While metadata registries handle the passive attributes of data elements, extensions are needed to handle the active attributes (behaviors, methods) of object oriented data and groups of data elements.

Object Technologies. How do we integrate metadata registries into object technologies such as CORBA and COM/DCOM? This requires appropriate APIs and services such as object query services.

IT enabled data standards. How can a metadata registry be used to improve the design of data? What is necessary to IT enable data standards (on paper) from international, national, government and private sources? The content of many standards needs to be restructured in order to record them in metadata registries and to deploy them in information systems.

Assemble-to-order data specifications. How can the (interchangeable data parts)--as registered in the metadata registry--be assembled into a variety of products: database designs, reports, EDI transaction sets, EDIFACT message sets, information collection requests, regulations, legislation, etc.?

Interchange. How can metadata registries facilitate all types of electronic data communication including: EDI, web enabled forms, HTML/XML documents, etc.

XML-DATA, Resource Description Framework. What requirements does the data registry community have for XML standards development efforts?

Intelligent Information Integration. What metadata is necessary to combine related data from different sources, which may require transformation between different physical representations, measurement units, and granularity (e.g., for data warehouses, multidimensional processing or ad hoc data integration)?

Understanding. How can a metadata registry help make specialized knowledge available to others who want to use the data? If someone from a different organization wants to use certain data ten years from now, what metadata will he/she need to make meaningful use of it?

Discovery. What structure and kinds of metadata are necessary to help humans and software find data they need from a search request -- maximizing both recall (the fraction of relevant data retrieved by a query), and precision (the ratio of relevant to total data retrieved by a query)?

Access. What detailed metadata on database schemas and data elements are necessary to access (query) data in relational databases and non-standard data repositories?

Complex data. What metadata is necessary to support derived, aggregate, and structured data such as: summarizing of (micro) data - e.g., grouping and aggregation, categorical, ordered, and metric data, relating among similar but different data element concepts, and data that has internal structure?

Related Standards. What other standards, which are not the focus of this Open Forum, can contribute to this endeavor? These could include terminology, thesaurus, conceptual schema, XML, SQL, digital library, knowledge interchange, and other standards. We look forward to interaction with standards developers and practitioners in these communities.

Metadata registries are a relatively new concept; registries may be established and operated by individual organizations (such as corporations or government agencies), or by larger aggregations such as trade associations and standards organizations.

xample Databases and Registries:


Prior to and during the Open Forum, a selected set of databases and prototype data registries will provide a common starting point of concrete examples.

Open Forum participants are encouraged to illustrate points in their presentations using a selected set of prototype databases, metadata registries, and metadata representations available over the World Wide Web. We hope that this common frame of reference and concrete examples will expedite discussion and encourage more specific understanding than might otherwise be the case. Example databases, registries, and representations include:

EPA Environmental Data Registry; including:

     Data elements from selected international, national, and federal standards
       (e.g., state codes from Federal Information Processing Standard, FIPS Pub 55),

     Data elements from selected organizational databases where there is an interest
        in sharing such data (e.g., EDI message/transaction sets).

National Health Information Knowledgebase - Australian Institute of Health and Welfare (AIHW), including metadata for the data in Australian healthcare systems.

Data Access and Dissemination System (DADS) prototype is an Internet data dissemination system being designed for 2000 Census, 1997 Economic Censuses, and American Community Survey data. The current prototype uses 1990 Census data in place of 2000 Census data. DADS is a metadata driven system and utilizes a comprehensive metadata registry model to organize its metadata. The model implements ISO/IEC 11179 and ANS X3.285.

U.S. Health Care Financing Administration registration of metadata (supporting the Healthcare Insurance Portability Accountability Act (HIPAA) of 1996 )

Basic Semantic Repository (BSR) (prototype registry for data description across various industry sectors for electronic data communication, including commerce-related EDI).

Harmonizing IS11179 and IS 9075 (Database Language SQL)
Bill Olle
T. William Olle Associates, U.K.

The re-engineering of JTC1 standardization activities has brought together the former JTC1 SC14 responsible for IS 11179 (Data Element Standardization and Specification) and the former SC21/WG3 responsible (among other things) for IS9075 (Database Language SQL). This presentation analyzes how the facilities identified in IS11179 can be harmonized with those already in world wide use in the many implementations of IS 9075 - and vice versa. The presentation concentrates mainly on IS 11179-3:1994 (Basic attributes of data elements) and considers also how an implementation of the IS 11179-3 concepts can be developed using an SQL product.

3:40 - 4:30

Harmonization of ISO/IEC standards 14662 Open-edi Reference Model and 11179 Data Element Standardization and Specification
Jake Knoppers
Canaglobe International, Inc.

The re-engineering of JTC1 standardization activities brought together former JTC1/SC14 responsible for 11179 (and now part of SC32/WG2) and former JTC1/SC30 responsible for 14662 (now SC32/WG1). Open-edi consists of three basic components "persons", "processes (or "roles") and data (or "semantic components"). Here "information bundles" serve to bind "roles" and "semantic components". The 11179 standard covers types of data elements broader than those which meet Open-edi criteria. On the other hand, the Open-edi Reference Model standard covers, in addition to data elements, expected behaviors as roles in the context of business scenarios. The purpose of this session is to provide an overview of how and where 11179 and 14662 standards complement each other and should interwork.

4:30 - 5:00

ISO/IEC CD 15452 Data Value Domains
Judith Newton
National Institute of Standards and Technology

ISO Technical Report 15452 Information Technology - Specification of data value domains addresses practical issues encountered in documenting and sharing data.  It describes a standardized process of definition and application of sets of possible valid values for data elements to assist in the sharing and reuse of information across national and international organizations.

This document complements and extends the attributes of data elements specified in ISO 11179.

Panel Discussions

This day will consist of several concurrent panels. Each panel will last from a half day. The intent is to introduce continuing work on standards related to ISO/IEC 11179 metadata registries. A "study period" for potential New Work Items (NWIs) was approved at the July 1998 meeting of SC 32/WG 2. The study period gives the green light to proceed full apace. During the study period, we are to identify the topics, lay out the issues, organize the efforts, create drafts and to generally prepare for JTC 1 NWI Proposal (NP) ballots. The JTC 1 directives encourage us to do considerable work before issuing a NP ballot, including preparation of a draft of the proposed standard. During this process, many changes may be made. As stated at the SC 32/WG 2 meeting, there is a potential for clumping and splitting the ideas contained in the original NWI proposals.

The Panel leaders (interim leaders for work on the new work items) are arranging the content and speakers. The intent for this day is to introduce the topics and to engage the broadest possible participation in the ongoing task of defining the issues and proposing draft standards.

Panel organizer: Tom Culpepper, 3M Health Information Systems

Panel Participants:
Eliot Christian, US Geological Survey
Glenn Sperle, DoD/Health Affairs
Robert Mayes, Health Care Finance Administration
Phong Ngo, Science Applications International Corp.

The focus of this New Work Item (NWI) is to provide object extensions to the ISO/IEC 11179 specification. The ISO/IEC 11179 is a multi-part International Standard concerning data element specification and standardization. The complete set includes six interrelated parts, with each part focusing on one aspect of data element development and maintenance.

This NWI will also focus on objectifying the 11179-1, 11179-2, 11179-4, 11179-5, 11179-6 parts in order to make it more useful for object-oriented system analysis, design and development.

ISO/IEC 11179, Part 3 "Basic Attributes of Data Elements" is being revised to include X3.285 "Metamodel for the Management of Shareable Data" which specifies the structure of a data registry. The structure is stated in the form of a conceptual data model and provides the attributes for identifying the characteristics of data that are necessary to clearly describe, inventory, analyze, and classify data. However, 11179 does not provide an interface that allows for interoperability in a distributed environment. This NWI will specify the behavioral aspects of a data registry. The behavior will be stated in the form of an interface specification better known as a Metadata Query Service. The Metadata Query Service will provide a way to access the information in a data registry in a well-defined way; thus, making it possible for applications to interoperate with another application by calling the services named in the interface. The utilization of such an interface could be realized in information technologies such as global information locator service's whose focus in geared at providing public, government, and industry sectors information discovery and retrieval facilities.

Panel 2 - Extend 11179 for Complex data

Panel organizer: Dan Gillman, U.S. Bureau of the Census

Panel Participants:
Cathryn Dippo, Bureau of Labor Statistics
Don Sawyer, National Aeronautics and Space Administration
Joe Christensen, Australian Institute of Health and Welfare

Current standards for data elements and registries (ISO/IEC 11179 and X3.285) address the structure and attributes of data elements at the fundamental level and a registry to store the information. A data element registry is designed to enable managing, understanding,   and sharing of data over the lifetime of that data. However, much data is generated by means of calculation, aggregation, composition, grouping, or other derivation methods. In addition, new complex data types in multimedia and advanced scientific applications are in wide use. The current standards do not address these complexities. As an incremental step toward a complete description of the data a registry describes, the specification of complex data will enable a deeper understanding for users of the data. This panel brings together experts from a variety of organizations that handle large amounts of data. The aim is to introduce issues on complex data and discuss the following:

a) how the needs of users are limited by the current structures in ISO 11179 and X3.285

b) what new attributes are necessary to describe

i) derived data

ii) multi-media data

c) possible ways to solve the problems.

Panel 3 - Technical Report on Registry Content

Panel organizer: Larry Fitzwater, U.S. Environmental Protection Agency

Panel Participants:
Pat Heinig, U.S. Department of Energy
Judith Newton, National Institute of Standards and Technology
Kathleen Gundry, Science Applications International Corporation

The exchange of metadata between ISO/IEC 11179 metadata registries depends not only on registry software that conforms to the standard, but also on metadata contents that are compatible between registries. While the standard has provisions for data element specification and registration, there are pragmatic issues pertaining to populating the registries with content. Based on the experiences of organizations that are implementing the standard, a technical report to explore content issues could help current and future users. This could also possibly be an implementation guide.

A major issue in this area is levels of abstraction for registry contents. At one end of the spectrum are "abstract" (generic, core, reference, …) data elements that are well formed, but not yet used in any application. At the other end of the spectrum are "application" data elements that are specified for a particular application, such as an EDI message, a reporting requirement, or a statistical survey. The abstract data elements are useful for managing domains. The application data elements are the level at which data is exchanged - wherein the purpose, statistical method for gathering the data and other relevant factors are important to specify in order to assure that potential use of the data are compatible with the "provenance" or "pedigree" of the data.

The Data Registry Community intends to develop a set of XML tags for 11179 metadata, just as other professional communities have developed tagsets such as MathML and ChemML. This work will help make ISO/IEC 11179 a useful part of new XML-enabled technologies. One goal of this effort is to facilitate interoperation among metadata registries. Another goal is to enable XML applications (such as XML-EDI) to directly access metadata registries using a standard syntax and semantics. This panel brings together experts from the ISO and NCITS committees responsible for 11179, World Wide Web Consortium (W3C) committees working on XML extensions, Electronic Data Interchange committees, and the Object Management Group (OMG) to discuss the opportunities and challenges of this 11179 XML tag set development effort.

"What Everyone Calls It": Mapping Users' Words and Terminologies

The Terminology project will focus on the standards and advanced technologies required to capture concepts (definitions) and linguistic expressions as terms within in a context, e.g., terms in use by specific languages or by specific scientific disciplines. Extensions may be needed for ISO/IEC 11179 in order to specify the terminology management capabilities required for metadata registries. Reference implementations will be used to demonstrate the practical utility of the proposed standards and technology. This is exploring the advanced technology and standards required to organize concepts (and related terms) into structured sets of concepts. The structured sets may take the form of data elements, thesauri, topic trees, taxonomies, and ontologies. These structured sets are useful in information system development and for use in Internet middleware such as search engines and intelligent information services. This work will include the demonstration of the use of an ontology for next generation public access systems.

Panel 6 - Revision of ISO/IEC 11179, Part 3

Project editor, panel organizer - Joe Christensen,
Australian Institute of Health and Welfare

Panel participants:
Dan Gillman, Bureau of Census
Douglas Mann, Pacific Northwest Laboratories

This is an effort to update ISO/IEC 11179, Specification and Standardization of Data Elements, Part 3, Basic Attributes of Data Elements. At the July 1998 meeting of SC32/WG2 in Brisbane, it was agreed that in response to the required five-year review of Part 3, we would prepare a revised version of Part 3. This revision of part 3 would be based on ANS X3.285, Metamodel for the Management of Shareable Data, which is the result of considerable work at the U.S. national level. ANS X3.285 incorporates virtually all of ISO/IEC 11179, Part 3, extends the list of attributes, and presents the structure of a data registry in the form of a model. It includes an informative annex with translations to several popular modeling notations.

In addition to revisions of Part 3, it will be necessary to develop corrigenda or changes in the other Parts of ISO/IEC 11179 to ensure they are consistent with each other and with the revised Part 3. As the ANS X3.285 model applies to all parts of ISO/IEC 11179, this will require particular attention.

Presentations of related work

This day is for presentations of material related to ISO/IEC 11179 metadata registries. Each session is concurrent with another.

Schedule:

9:00 - 10:00 Concurrent Sessions:

Lexicon Query Service
Tom Culpepper or Harold Solbrig, 3M Health Information Systems

The Lexicon Query Service (LQS) is a read-only specification for accessing the content of medical terminology systems. The LQS is an adopted Object Management Group (OMG) standard. It was developed by the CORBAmed Domain Task Force under OMG. The Lexicon "L" portion of the LQS deals with terminology and the underlining terminology model. The Query Service "QS" portion of the LQS deals with accessing information in a well-defined way.

Environmental Data Exchange Network
Jerry Fowler, MCC

The Environmental Date Exchange Network (EDEN) is a collaborative project between the Environmental Protection Agency, Department of Defense, Department of Energy and the European Environment Agency.  This project is demonstrating Intelligent Information Services technologies including query agents, brokers, and resource agents.  This enables users to obtain data from databases spread across the organizations involved via ontology base queries.  The 11179 metadata registry can both documents the data and provide mapping services to convert between different representations of equivalent data.


10:00 - 10:45
Concurrent Sessions:

IT-enablement of Data Element-based Standards (with Support of Localization and Multilingual Requirements)
Jake Knoppers, Canaglobe International Inc.

Electronic commerce, particularly business-to-business applications, consists of rule-based transactions that make extensive use of codes, often through tables, representing predefined possible choices of common aspects of business transactions. Examples include countries, currencies, languages, commodities, etc. Information technology (IT) enablement is the term used to recognize the need to transform such currently accepted standards from a manual to a computerized perspective. Localization and multi-lingualism focuses on the need to identify objects in an unambiguous, linguistic neutral way that can be processed electronically. In this way cultural and linguistic needs of end-users become primarily a human-interface issue. The presentation will use the practical examples noted above from an IT-enablement perspective also meeting localization and multilingual requirements.

 

The Metadata Sweetspot
-The optimum time and place for enforcing and capturing metadata

Rick Orli
Technical Director
Kismet Analytic Corp

Kismet Analytic Corp. has a commercial metadata standards tool that enforces 11179 and is developing another tool that will help automatically rationalize metadata and would work very well as part of a registry environment.

10:45 - 11:00 Break

11:00 - Noon, Concurrent Sessions:

Model for Metadata for Multimedia Information
CEN/ISSS Workshop on Metadata for Multimedia Information
Stewart Granger
Southampton University
This group proposes a high level conceptual model for metadata for multimedia information in terms of classes of metadata, the roles of the different actors involved and the actions performed by each role. At the conceptual level, the same concepts and lifecycle model can be applied to both information resources and metadata.

101 Metadata Schemas (Indecs)
Godfrey Rust
Data Definitions, London, England

The INDECS (Interoperability of Data in E-Commerce Systems) project
was established to integrate initiatives including: the copyright
societies Common Information System, the record industry's ISRC and
MUSE projects, the audiovisual ISAN initiative, the text publishing
industries' ISBN and ISSN and the Digital Object Identifier (DOI).
INDECS is developing specific common standards and tools that enable
interoperability of identifiers and metadata.

Noon - 1:30       Lunch

1:30 - 2:30
Concurrent Sessions:

1:30 - 2:30

Global Information Locator Service & National Spatial Data Infrastructure
Eliot Christian, United States Geological Survey

The Global Information Locator Service (GILS) promotes standards for network searching of information. This approach enables virtual libraries of data and information that have useful interoperability yet are as diverse and decentralized as participating communities need to be. Standards adopted for this service currently include common Internet facilities and the international standard for information search, ISO 23950 (ANSI Z39.50).

1:30 - 2:00

Building Tools To Enhance Registry Metadata Input, the MedQuest Example
Robert Mayes
Director, Information Systems Group
Health Care Financing Administration

MedQuest is a software design tool created by the Health Care Financing Administration to support the development of clinically-oriented data collection and analysis systems. MedQuest is based on the concept of expanded data dictionaries. Recent enhancements to the tool set include the ability to easily export the created data dictionaries in ISO 11179 format. This allows for the population of metadata registries directly as a function of application development, thus potentially greatly reducing the administrative burden of maintaining the registry.

2:00 - 2:30

Extensions - Statistical Metadata Extension to X3.285 Metamodel
Dan Gillman, Bureau of Census

In support of the work to build a statistical metadata registry (see implementation description for day 2), the Census Bureau built extensions to the X3.285 metamodel. This talk will discuss the need to build context into a registry model and describe why the extensions provide this.

An overview of the extensions to the model will be discussed. Ways in which the design of the X3.285 metamodel were exploited to extend the notions of administered components, registration, and classification are described. Finally, the use of the metamodel to lay the groundwork for crosswalks between is discussed.

2:30 - 3:30 Concurrent Sessions:

XML-Data/RDF for ISO/IEC 11179
Frank Olken
Computer Scientist
Lawrence Berkeley National Laboratory

The W3C XML-Schema Working Group is currently working on several issues which could have an impact on metadata registries in general, and ISO/IEC 11179 in particular. This presentation will discuss these issues, including datatype definitions, data structures, lexical scoping, and namespaces.

Standards for the Global Digital Marketplace and the Canadian Electronic Commerce Strategy
David Clemis, Manager,Voluntary Standards, Industry Canada

International standards are certainly the best available means of achieving the goal of free trade without obstacles in the form of technical barriers. They are essential to the development of new markets and to building confidence of consumers, manufacturers and service providers. Interoperability of standards and electronic business practices is critical for the growth of digital markets, determining their size, openness and efficiency. For electronic commerce to be globally adapted, common standards for both interoperability and language independent communications are required. This session presents the Canadian Electronic Commerce Strategy within the international context and positions "data" as one of the three key components of the Canadian E-Commerce Model
